THOUSANDS STAND SHOULDER-TO-SHOULDER WITH AT AN EMOTIONAL VIGIL TO PULSE VICTIMS IN ORLANDO

Vigil: Thousands gathered to mourn, remember and heal at a vigil in Orlando Monday night for those slain in a shooting at city gay club Pulse at the weekend. Omar Mateen opened fire in the nightclub early Sunday morning, killing 49 and injuring 53

As vigil took place across the globe, in Orlando itself thousands came together to pay their respects to the 49 people who died in the Pulse nightclub shooting.

People gathered on the lawn outside the Dr Phillips Center for the Performing Arts, where they observed a moment's silence and a bell tolled 49 times for the victims.

Speaking at the vigil were leaders from the LGBT, Muslim and Latino communities as well as the friends and families of those that died, whose names were read aloud.

Masses: There were people from all walks of Orlando life at the event, gathering to mourn, remember and hope for a better future

Unity: Many of those in attendance were from the city's LGBT community. Speakers talked of the need to unite across all boundaries, and not to submit to 'homophobia, transphobia, xenophobia, Islamophobia'

Mourners also created a makeshift shrine of flowers, candles and notes for the victims, with many saying they felt compelled to attend because of the important role Pulse played in their lives.

Barbara Poma and Ron Legler, founders of Pulse also stepped up to the stage to promise that they would restore the club's promise to be a place of safety for the LGBT community.

Legler caught the crowd up in a chant of 'Peace! Love! Pulse!' and invited the audience to engage in a group hug with their neighbors.

'We have to live in a society where homophobic hate crime is a thing of the past and the deaths that happened in Orlando are a sign of something deeply awful.

'We're here in Old Compton Street because of what happened here and it's that sense of solidarity that we've got.

'Love, in the end, defeats this crime, because it's stronger.'

Following the two minutes of silence, the group - which also featured shadow chancellor John McDonnell and Scottish Conservative leader Ruth Davidson - laid flowers at St Anne's Church to those killed in the atrocity.

Nicky Morgan, who is also equalities minister, said of her decision to appear alongside members of opposing parties: 'I think this sort of tragic, horrific event in Orlando transcends normal party politics and we all wanted to be here to offer our solidarity with the people of Orlando who have suffered the most awful hate crime, fuelled by prejudice.

'I think it is very important - and quite moving - that the streets of London were filled with so many people who wanted to pay their tribute.'

Jerry and Ginger Updike, both from Orlando, had a friend who worked at the bar but had not been at the scene on the night of the killings.

'Orlando is probably the most LGBT friendly city, along with San Francisco and New York, and to have that happen in our own backyard is just surreal,' Mr Updike said.

'It's really amazing to see this event, right now we can't even do this in Orlando because the police have asked our friends not to do anything to detract from their resources because they need them to process what took place.

'I know that all around Florida and here we're getting a chance to do what those in Orlando aren't able to do right now - it feels good.'

Bradley Odd, another member of the LGBT community who had come down to pay his respects, said the killings had made him feel more fearful of going out.

He said: 'Growing up I was always afraid to go to gay bars anyway because you still get stories in the press every now and again of drive-by acid attacks.

'So when you finally start to come to terms with yourself and something like this happens, then it just reinforces that kind of stuff.'

He added: 'It might make me more reluctant to go out, but I'd still go out anyway because I think that is what people need to do.

Hundreds of people also lit candles and laid flowers in Glasgow as the names of the victims gunned down were read aloud in George Square.

Rainbow Pride flags - a symbol of the lesbian, gay, bisexual, and transgender (LGBT) community - were planted in the square and cards and messages were laid beside flowers and candles.

Glasgow Mayor Sadie Docherty told the 600-strong crowd that the city stood in solidarity with Orlando as she placed a bouquet in the square which had a Scottish and US flag inside it.

Earlier, the Pride flag was raised at the Scottish Government's headquarters in Edinburgh. A similar vigil has also been organised in Edinburgh on Wednesday.

First Minister Nicola Sturgeon tweeted: 'Scotland stands in solidarity with the people of Orlando, and LGBTI communities across the world.'

The flag was also flying at half mast above Glasgow City Chambers, overlooking George Square.

Scottish Labour leader Kezia Dugdale, who confirmed she was gay two months ago, described the attack as 'utterly heart-breaking'.

She said: 'This looks to have been an attack on the very freedom to love who you want to love. We stand in solidarity with the entire LGBT community and the vast majority of Americans who will oppose this hate.'

The Sydney Harbour Bridge is illuminated with rainbow colors to remember victims of the Orlando night club massacre

Human rights campaigner Peter Tatchell and former Green Party leader Natalie Bennett - along with thousands of Londoners - stood together in solidarity tonight with those who died in the Orlando massacre.

Mr Tatchell, 64, held a poster which read 'Commemorate Orlando victims - schools must educate against hate' at the well-attended vigil on Old Compton Street at the heart of London's gay village.

The veteran human rights campaigner said it was crucial that gay venues and events in Britain 'redoubled their security'.

He said: 'The vigil was a huge act of solidarity and defiance. We are here, we are queer and we refuse to live in fear.

'Given the attack in Orlando it is common sense that gay venues and events need to improve their security. If that means more bag searches then so be it. The number one priority is to insure that gay venues are safe and secure places.'

Ms Bennett, 50, who was one of several politicians to attend the vigil in Soho, also held up a poster to show solidarity with the LGBT community.

She said: 'We're standing right outside the Admiral Duncan where not that long ago we saw a similar attack.'

She said of the vigil: 'I would have thought there were at least six to eight thousand people here on Old Compton Street.

'Politics should be something you do not something that is done to you and to stop homophobia people should stand up against discrimination.

'There should be human rights for everybody. It was very moving. It was two minute of absolute silence, of three people coming together.'

Mr Tatchell added: 'I suspect that the London LGBT pride this year will be bigger than ever.

'There will be a very strong focus of solidarity.

'It is truly shocking. The bloody scale of this massacre is almost beyond comprehension.'

Tom Bollman, 32, who attended the London vigil with his husband Derek Fhuff, believes the sickening attack at Pulse nightclub was particularly shocking because it took place at a venue where gay people feel safest.

Mr Bollman, born in San Diego but who has lived in London for 11 years, said of the vigil: 'It was great. It's excellent that so many people came out to support the people of Orlando.

'I went to Pulse during an event called Gay Day Orlando six years ago and it was great, I had a lot of fun.

'It's quite a popular club among our community.

'The security then was pretty relaxed: they pat you down and that was it. They do not check you, unless you have a bag.

'In Orlando the guy just stormed the place. I don't think there was a lot that could be done.'

Tom, who works as a para-legal in London, added: 'I do not feel threatened coming out in Soho, but in other places I have to think about whether it's safe to hold my husband's hand.

'The fact that the massacre was at a gay bar where people usually feel safe and relaxed is part of why it was so shocking.

'That, I think, is what's brought people out in solidarity.'

An outpouring of sympathy streamed in from around the world as millions reacted to the Florida mass shooting, with millions taking to social media to post their shock and write messages of support for the victims, angry that part of the killer's motive for the attack appears to have been the sexuality of his victims.

The hashtag #LoveWins, which went viral last year after the same-sex marriage ruling by the U.S. Supreme Court, is now being used to show support for those shot in the Pulse gay nightclub in Orlando.

Millions have also commented under #loveislove on Twitter.

Crowds flocked to vigils around the world on Monday in shock at the shooting of dozens of Florida club-goers in the deadliest ever attack targeting gay people.

Thousands lined the streets in the central London district of Soho, long a hub for the gay community in Britain, bursting into chants of 'we're here, we're queer, we will not live in fear' under rainbow flags.

A policeman at the scene estimated the crowd at between 5,000 and 7,000 strong, as other rallies took place in cities from Berlin to Bangkok.

The crowd in London released 49 brightly coloured balloons into the sky for each one of the victims of Sunday's massacre at the gay nightclub in Orlando, the worst mass shooting in modern US history.

And they stood outside the Admiral Duncan, a pub where three people died when a neo-Nazi planted a nail bomb in a homophobic attack in 1999

In 1999, neo-Nazi nail bomber David Copeland attacked three targets in London in 1999.

Three people died at the Admiral Duncan gay pub in Soho.

He had placed homemade nailbombs, each containing up to 1,500 four-inch nails, in holdalls that he left in public spaces around London - including Brixton, Brick Lane and Soho.

The fatal bomb in Soho killed three people, including a pregnant woman, and injured 140, four of whom lost limbs.

Copeland was jailed for targeting Brick Lane, Soho and Brixton in a 13-day nail bombing campaign that left three people dead and 139 injured.
